Exploring the publications in three major orthodontic journals: a comparative analysis of two 5-year periods.

OBJECTIVE To analyze the types of articles and authorship characteristics of three orthodontic journals--American Journal of Orthodontics and Dentofacial Orthopedics (AJODO), The Angle Orthodontist (AO), and European Journal of Orthodontics (EJO)--published between 2008 and 2012 and to assess the differences in content within this period and an earlier period of 1998 to 2002. MATERIALS AND METHODS Each journal's content was accessed through the web edition. From each article, the following parameters were recorded: article type, number of authors, number of affiliations, source of article (referring to the first author's affiliation), and geographic origin. Descriptive statistics were performed and selected parameters were analyzed with the Pearson chi-square or Fisher exact test for independence at the .05 level of significance. RESULTS Review of differences between the two periods showed that the number of publications was almost double. The percentages of multi-authored articles increased. Fewer studies derived from the United States/Canada and European Union countries. Increases for articles from non-European Union countries, Asia, and other countries were found. Characteristics of the second period showed that the EJO and AO published more research articles, whereas the AJODO regularly published case reports and other articles. Approximately 75% of all studies derived from orthodontic departments. CONCLUSIONS The publications from 1998-2002 and 2008-2012 were significantly different both in terms of numbers and characteristics. Within 2008-2012 there were notable differences between the three journals concerning the type and origin of the publications.

Controversies in the use of hydroxyethyl starch solutions in small animal emergency and critical care

OBJECTIVES: To (1) review the development and medical applications of hydroxyethyl starch (HES) solutions with particular emphasis on its physiochemical properties; (2) critically appraise the available evidence in human and veterinary medicine, and (3) evaluate the potential risks and benefits associated with their use in critically ill small animals. DATA SOURCES: Human and veterinary original research articles, scientific reviews, and textbook sources from 1950 to the present. HUMAN DATA SYNTHESIS: HES solutions have been used extensively in people for over 30 years and ever since its introduction there has been a great deal of debate over its safety and efficacy. Recently, results of seminal trials and meta-analyses showing increased risks related to kidney dysfunction and mortality in septic and critically ill patients, have led to the restriction of HES use in these patient populations by European regulatory authorities. Although the initial ban on the use of HES in Europe has been eased, proof regarding the benefits and safety profile of HES in trauma and surgical patient populations has been requested by these same European regulatory authorities. VETERINARY DATA SYNTHESIS: The veterinary literature is limited mostly to experimental studies and clinical investigations with small populations of patients with short-term end points and there is insufficient evidence to generate recommendations. CONCLUSIONS: Currently, there are no consensus recommendations regarding the use of HES in veterinary medicine. Veterinarians and institutions affected by the HES restrictions have had to critically reassess the risks and benefits related to HES usage based on the available information and sometimes adapt their procedures and policies based on their reassessment. Meanwhile, large, prospective, randomized veterinary studies evaluating HES use are needed to achieve relevant levels of evidence to enable formulation of specific veterinary guidelines.

Exploring the emotional brain: Neural correlates of homeostatic and sensory-evoked emotions and their interaction in emotional rivalry

Human emotions are essential for survival. They are vital for the satisfaction of basic needs, the regulation of personal life and successful integration into social structures. Depending on which aspect of an emotion is used in its definition, many different theories offer possible answers to the questions of what emotions are and how they can be distinguished. The systematic investigation of emotions in cognitive neuroscience is relatively new, and neuroimaging studies specifically focussing on the neural correlates of different categories of emotions are still lacking. Therefore, the current thesis aimed at investigating the behavioural and neurophysiological correlates of different human emotional levels and their interaction in healthy subjects. We differentiated between emotions according to their cerebral entry site and neural processing pathways: homeostatic emotions, which are elicited by metabolic changes and processed by the interoceptive system (such as thirst, hunger, and need for air), and sensory-evoked emotions, which are evoked by external inputs via the eyes, ears or nose, or their corresponding mental representations and processed in the brain as sensory perception (e.g. fear, disgust, or pride). Using functional magnetic resonance imaging (fMRI) and behavioural parameters, we examined both the specific neural underpinnings of a homeostatic emotion (thirst) and a sensory-evoked emotion (disgust), and their interaction in a situation of emotional rivalry when both emotions were perceived simultaneously. This thesis comprises three research articles reporting the results of this research. The first paper presents disgust-related brain imaging data in a thirsty and a satiated condition. We found that disgust mainly activated the anterior insular cortex. In the thirsty condition, however, we observed an interaction effect between disgust and thirst: when thirsty, the subjects rated the disgusting stimulus as less repulsive. On the neurobiological level, this reduction of subjective disgust was accompanied by significantly reduced neural activity in the insular cortex. These results provide new neurophysiological evidence for a hierarchical organization among homeostatic and sensory-evoked emotions, revealing that in a situation of emotional conflict, homeostatic emotions are prioritized over sensory-evoked emotions. In the second paper, findings on brain perfusion over four different thirst stages are reported, with a special focus on the parametric progression of thirst. Cerebral perfusion differences over all thirst stages were found in the posterior insular cortex. Taking this result together with the findings of the first paper, the insular cortex seems to be a key player in human emotional processing, since it comprises specific representations of homeostatic and sensory-evoked emotions and also represents the site of cortical interaction between the two levels of emotions. Finally, although this thesis focussed on the homeostatic modulation of disgust, we were also interested in whether dehydration modulates taste perception. The results of this behavioural experiment are described in the third paper, where we show that dehydration alters the perception of neutral taste stimuli.

Immune response to hepatitis B vaccination in drug using populations: A systematic review and meta-regression analysis

Hepatitis B virus (HBV) is a significant cause of liver diseases and related complications worldwide. Both injecting and non-injecting drug users are at increased risk of contracting HBV infection. Scientific evidence suggests that drug users have subnormal response to HBV vaccination and the seroprotection rates are lower than that in the general population; potentially due to vaccine factors, host factors, or both. The purpose of this systematic review is to examine the rates of seroprotection following HBV vaccination in drug using populations and to conduct a meta-analysis to identify the factors associated with varying seroprotection rates. Seroprotection is defined as developing an anti-HBs antibody level of ≥ 10 mIU/ml after receiving the HBV vaccine. Original research articles were searched using online databases and reference lists of shortlisted articles. HBV vaccine intervention studies reporting seroprotection rates in drug users and published in English language during or after 1989 were eligible. Out of 235 citations reviewed, 11 studies were included in this review. The reported seroprotection rates ranged from 54.5 – 97.1%. Combination vaccine (HAV and HBV) (Risk ratio 12.91, 95% CI 2.98-55.86, p = 0.003), measurement of anti-HBs with microparticle immunoassay (Risk ratio 3.46, 95% CI 1.11-10.81, p = 0.035) and anti-HBs antibody measurement at 2 months after the last HBV vaccine dose (RR 4.11, 95% CI 1.55-10.89, p = 0.009) were significantly associated with higher seroprotection rates. Although statistically nonsignificant, the variables mean age>30 years, higher prevalence of anti-HBc antibody and anti-HIV antibody in the sample population, and current drug use (not in drug rehabilitation treatment) were strongly associated with decreased seroprotection rates. Proportion of injecting drug users, vaccine dose and accelerated vaccine schedule were not predictors of heterogeneity across studies. Studies examined in this review were significantly heterogeneous (Q = 180.850, p = 0.000) and factors identified should be considered when comparing immune response across studies. The combination vaccine showed promising results; however, its effectiveness compared to standard HBV vaccine needs to be examined systematically. Immune response in DUs can possibly be improved by the use of bivalent vaccines, booster doses, and improving vaccine completion rates through integrated public programs and incentives.^

Arthropoda abundance along an elevation gradient on the southern slopes of Mount Kilimanjaro, Tanzania

Species diversity is the most common variable reported in recent ecological research articles. Ecological processes, however, are driven by individuals. High abundances make arthropods, despite their small body sizes, important actors in food webs. We sampled arthropod assemblages in disturbed and undisturbed vegetation types along an elevation gradient of from 800 to 4550 m a.s.l. on the southern slopes of Mt. Kilimanjaro, Tanzania. In our analysis, we focused on 13 different lineages of arthropods that represented three major functional groups: predators, herbivores and decomposers. The samples were collected with pitfall traps on 59 (of 60) study sites within the framework of the KiLi-project (https://www.kilimanjaro.biozentrum.uni-wuerzburg.de/). In each of twelve vegetation types five sampling sites of 50 m x 50 m were established with a minimum distance of 300 m between the individual sites. On each of the 59 sites, ten pitfall traps were evenly spaced along two 50 m transects, with a distance of 10 m between individual traps and 20 m between the parallel transects. Pitfall traps were filled with 100-200 ml of a mixture of ethylenglycol and water (1:1) with a drop of liquid soap to break surface tension. Traps were exposed at 2 to 5 sampling events for seven days in both the dry and wet seasons between May 2011 and October 2012. The reported abundances per lineage were averaged twice: first over all samples per site for each sampling event (3-10 analyzed samples per site and sampling event), and then averaged over all sampling events for each site.

Implementación del modelo RIM de HL7 v3 en orientación a objetos y su uso en procesos de interoperabilidad semántica

El trabajo ha sido realizado dentro del marco de los proyectos EURECA (Enabling information re-Use by linking clinical REsearch and Care) e INTEGRATE (Integrative Cancer Research Through Innovative Biomedical Infrastructures), en los que colabora el Grupo de Informática Biomédica de la UPM junto a otras universidades e instituciones sanitarias europeas. En ambos proyectos se desarrollan servicios e infraestructuras con el objetivo principal de almacenar información clínica, procedente de fuentes diversas (como por ejemplo de historiales clínicos electrónicos de hospitales, de ensayos clínicos o artículos de investigación biomédica), de una forma común y fácilmente accesible y consultable para facilitar al máximo la investigación de estos ámbitos, de manera colaborativa entre instituciones. Esta es la idea principal de la interoperabilidad semántica en la que se concentran ambos proyectos, siendo clave para el correcto funcionamiento del software del que se componen. El intercambio de datos con un modelo de representación compartido, común y sin ambigüedades, en el que cada concepto, término o dato clínico tendrá una única forma de representación. Lo cual permite la inferencia de conocimiento, y encaja perfectamente en el contexto de la investigación médica. En concreto, la herramienta a desarrollar en este trabajo también está orientada a la idea de maximizar la interoperabilidad semántica, pues se ocupa de la carga de información clínica con un formato estandarizado en un modelo común de almacenamiento de datos, implementado en bases de datos relacionales. El trabajo ha sido desarrollado en el periodo comprendido entre el 3 de Febrero y el 6 de Junio de 2014. Se ha seguido un ciclo de vida en cascada para la organización del trabajo realizado en las tareas de las que se compone el proyecto, de modo que una fase no puede iniciarse sin que se haya terminado, revisado y aceptado la fase anterior. Exceptuando la tarea de documentación del trabajo (para la elaboración de esta memoria), que se ha desarrollado paralelamente a todas las demás. ----ABSTRACT--- The project has been developed during the second semester of the 2013/2014 academic year. This Project has been done inside EURECA and INTEGRATE European biomedical research projects, where the GIB (Biomedical Informatics Group) of the UPM works as a partner. Both projects aim is to develop platforms and services with the main goal of storing clinical information (e.g. information from hospital electronic health records (EHRs), clinical trials or research articles) in a common way and easy to access and query, in order to support medical research. The whole software environment of these projects is based on the idea of semantic interoperability, which means the ability of computer systems to exchange data with unambiguous and shared meaning. This idea allows knowledge inference, which fits perfectly in medical research context. The tool to develop in this project is also "semantic operability-oriented". Its purpose is to store standardized clinical information in a common data model, implemented in relational databases. The project has been performed during the period between February 3rd and June 6th, of 2014. It has followed a "Waterfall model" of software development, in which progress is seen as flowing steadily downwards through its phases. Each phase starts when its previous phase has been completed and reviewed. The task of documenting the project‟s work is an exception; it has been performed in a parallel way to the rest of the tasks.

Alfabetização no ensino fundamental: novas bases curriculares

Esta dissertação apresenta dados e discussões oriundos de uma experiência coletiva de pesquisa cujo objetivo maior consistiu em articular as bases curriculares da alfabetização no ensino fundamental de nove anos. A partir da transição histórica e política ocorrida pela Lei 11.274/1996, na qual o ensino fundamental passou a ter um ano a mais de duração e a receber as crianças que anteriormente eram atendidas na educação infantil, uma nova configuração se fez necessária. Demonstramos ao longo do trabalho a necessidade de: 1. Um plano que considere as transições (seja entre anos ou entre ciclos) e que sustente as continuidades; 2. Assumir, a partir do ano de ingresso no ensino fundamental, a perspectiva do regime de ciclo, definindo responsabilidades, objetivos e estratégias articuladas a partir de um trabalho em equipe; 3. Aprofundar conhecimentos que permitam considerar os aspectos mais subjetivos da relação educativa, considerando sempre a infância em seu encantamento lúdico; 4. Estabelecer uma relação dinâmica e produtiva entre oralidade e escrita, entre língua e literatura; 5. Dar maior precisão ao manejo da heterogeneidade desde a série de ingresso enfatizando o acompanhamento de singularidades e diferenças como forma de resolver o problema dos desníveis em alfabetização. A perspectiva teórica parte da articulação de várias áreas e temas do conhecimento: a história da escrita; pesquisa sobre oralidade ou cultura oral em tensão com a escrita; a psicanálise e a educação. Pretendemos, a partir das experiências e reflexões apresentadas nesse trabalho, contribuir para as políticas públicas enfatizando a grande relevância do ensino da escrita e da leitura nas séries iniciais do ensino fundamental. Ao longo dessas experiências, constatamos que, para formar leitores e escritores de bom nível na escola pública brasileira, precisamos de um modelo de trabalho coletivo mais complexo, capaz de exercer um manejo pedagógico detalhado, e ampliamos nossa consciência de que nossas buscas metodológicas, nossas experiências e nossos esforços coletivos em torno da heterogeneidade, apesar de consistentes e relevantes, só poderão ser sustentados a partir de uma reorganização do trabalho escolar que insista em fazer da alfabetização e da leitura uma verdadeira prioridade.

Potential impact of Wild boar (Sus scrofa) on Pheasant (Phasianus colchicus) nesting success

In recent decades wild boar have greatly increased in Europe due a combination of environmental and human factors. Because of a high reproduction rate, wild boar cause conflicts with human activities and in particularly agriculture. However, there are concerns also about environmental impact and in particular on ground nesting birds. Our study aim to evaluate the potential impact of wild boar on pheasants nests. Predation rates were compared between two areas with different wild boar abundance and between nests placed in fenced plots with no wild boar access (but accessible to other predators) and open plots in which the wild boar gains access. Predation rate by wild boar in the area with higher wild boar abundance was 61.5% whereas in the area with lower abundance was 16.0%. In plots with free access, wild boar predation was 34.2% whereas in exclusion plots we did not registered predation by wild boar. Moreover, wild boar resulted the main nest predator (total loss 22.8%). Our findings suggest that wild boar could have e strong impact on pheasant reproductive success.

Local community perception towards bats (Mammalia: Chiroptera) in Caves in South central Mindanao, Philippines: Threats and Implication for conservation

In the tropics, bats are an essential component of many native ecosystems, through providing various ecological services including pollination and insect pest control, in addition to seed dispersal. Many Philippine bat species roost in caves and underground habitats. However, many caves are disturbed by people, to exploit resources for food, recreation, and mineral and guano extraction. The misunderstanding of the importance of bats to the ecosystem is also considered a threat to many cave roosting species. Understanding the conflicts between humans and ecosystems which provide essential services is important to maintain ecosystem service provision. A total of 100 local respondents from the village of Pisan, Kabacan North Cotabato in south central Mindanao were interviewed through semi-structured interviews and focus group discussions. Respondents were asked about their views, levels of knowledge, use, interaction, and awareness towards both the caves and bats in their locality. Our survey found that most of the respondents are aware of the presence of bats from the caves in their locality. Unfortunately, a large proportion of the respondents noted that bats are hunted in caves for bush meat and trade, and most people perceived bats as pest to fruit crops such as durian. These factors are among the main factors of the execution of many bat colonies in caves of south central Mindanao. In general, cave bats are under appreciated species in caves. The unregulated tourism, hunting for bush meat and trade, and guano extraction are among the alarming threats occurring for both caves and bats in the locality and possibly to other localities in the country. Furthermore, the establishment of strong and effective model conservation education programs and the strengthening the participation of local government, academic, and community are essential steps to preserve the current state of cave bats in the area.

Factors Affecting Jaguar and Puma Predation on Livestock in Costa Rica

The wild cats and the livestock farmers are part of the space conflict in the rural areas in Latin America. In this sense, this conflict causes a discomfort among the livestock producers due to the loss of animals and, consequently, it also causes a negative reaction towards the wild cats leading such reaction into the elimination of the wild cats per se. Although, there have been some initiatives have tried to approach such conflict by recommending mitigation and prevention measurements to the producers, these measurements are undertaken without coordination. For this reason, the following project presents a planning tool that can ease the coordination processes undertaken for the solving of the conflict between human beings and wild cats.

Le sentiment d'appartenance à l'école : un regard conceptuel, psychométrique et théorique

Parce qu’il est notamment lié à des facteurs de réussite scolaire et d’adaptation sociale (Eccles & Roeser, 2009; Finn, 1989; Janosz, Georges, & Parent, 1998), le sentiment d’appartenance des élèves est considéré comme étant un élément de première instance qui doit d’être développé et maintenu par les professionnels de l’éducation (MELS, 2012). L'objectif général visait à approfondir notre compréhension du sentiment d’appartenance à l’école. Pour répondre à cet objectif général, trois articles de recherche distincts ont été élaborés. Le premier article présente une analyse conceptuelle visant à clarifier la compréhension du concept de sentiment d’appartenance à l’école. La méthode conceptuelle privilégiée dans cet article est celle de Walker et Avant (2011). La recension des écrits et les référents empiriques répertoriés indiquent que ce concept est de nature multidimensionnelle. L’analyse des données indique quatre attributs définitionnels. L’élève doit : (1) ressentir une émotion positive à l’égard du milieu scolaire; (2) entretenir des relations sociales de qualité avec les membres du milieu scolaire; (3) s’impliquer activement dans les activités de la classe ou celles de l’école; (4) percevoir une certaine synergie (harmonisation), voir même une similarité, avec les membres de son groupe. À la suite de cette étude permettant de mieux comprendre le sentiment d’appartenance à l’école, le deuxième article visait à examiner la structure factorielle et l'invariance de l’instrument de mesure du sentiment d’appartenance Psychological Sense of School Membership (PSSM) au regard du sexe des élèves. Cette étude a été menée chez un échantillon composé de 766 filles et de 391 garçons de troisième secondaire. Les analyses factorielles confirmatoires ont indiqué une structure à trois facteurs : (1) la qualité des relations entre les élèves; (2) la qualité des relations entre les élèves et l’enseignant; ainsi que (3) le sentiment d’acceptation par le milieu. Les analyses factorielles multigroupes ont indiqué pour leur part que le PSSM est un instrument invariant chez les filles et les garçons de troisième secondaire. Finalement, le troisième article a été mené chez un échantillon de 4166 élèves de niveau secondaire afin d’examiner les processus psychologiques complexes s’opérant entre le sentiment d’appartenance et le rendement scolaire (Anderman & Freeman, 2004; Connell & et al., 1994; Roeser et al., 1996). Afin d’examiner ces processus psychologiques, quatre hypothèses issues du modèle de Freeman-Anderman ont été validées par le biais d’analyses acheminatoires : H1 Les affects positifs médiatisent partiellement et positivement l’effet du sentiment d’appartenance sur l’engagement comportemental; H2 Les affects positifs médiatisent partiellement et positivement l’effet du sentiment d’appartenance sur l’engagement affectif; H3 Les affects positifs médiatisent partiellement et positivement l’effet du sentiment d’appartenance sur l’engagement cognitif; H4 Les engagements affectif, cognitif et comportemental médiatisent partiellement et positivement l’effet du sentiment d’appartenance sur le rendement scolaire. Nos résultats appuient partiellement la première hypothèse de recherche tout en soutenant les hypothèses deux, trois et quatre. Spécifiquement, la relation entre le sentiment d’appartenance et l’engagement émotionnel montre davantage un effet direct qu’un effet indirect (H2). L’étude a produit des résultats similaires pour l’engagement cognitif (H3). Finalement, la relation entre le sentiment d’appartenance et le rendement scolaire indique un effet indirect plus grand qu’un effet direct (H4). À la lumière de ces résultats, des recommandations à l’intention des professionnels de l’éducation sont offertes en guise de conclusion.

Authors' institutional affiliations in Australian intellectual and developmental disabilities journals: a comparison of two decades

The generation of new knowledge through research can contribute significantly to the improvement of services for individuals with intellectual and developmental disabilities. This study extends a previous study by Sigafoos, Roberts, and Couzens [Aust. N.Z.J. Dev. Disabil. 17 (1991) 331] by examining research productivity in intellectual and developmental disability in Australian journals for 1990-1999. Institutions that published research articles on intellectual and developmental disabilities in Australian journals in the 1990s were identified by noting the affiliations of authors. The most productive institutions were primarily universities in Australia and the United States of America. Publication trends in the decade of the 1990s are compared with trends of the previous decade (1980-1990). (C) 2003 Published by Elsevier Ltd.
